Definitions

  • the present invention relates to a method and to an installation for producing a powdery porous product.
  • the invention is more specifically interested in the case of the production of powdery porous products from an initial viscous product, the obtained products being typically so called instantaneous powders, which are for example mixed with water or with other liquids for obtaining, by rehydration of the powders, a homogeneous liquid.
  • EP-A-1 133 923 discloses a method of this type, for which the main steps consists of:
  • WO-A-2008/046996 discloses a method and an installation of this type, wherein the viscous initial product is, before being mixed with gas in an aerator for forming a liquid foam which is then divided and dried for obtaining a powdery porous product, subject to the action of a thermomechanical treatment machine, typically an extrusion machine.
  • a thermomechanical treatment machine typically an extrusion machine.
  • the viscous initial product is mechanically worked, notably subject to controlled shearing, and/or thermoregulated in order to condition at best with view to its admission in the aerator.
  • thermomechanical treatment machine for producing a first mixture between the viscous initial product and a gas, in order to initiate porosity in the treated material, the mixture of the latter with gas being intensified in the aerator connected in continuity with the extrusion machine.
  • WO-A-2013/185941 is interested in a more specific production of powdery porous products, i.e. those containing probiotics or similar microorganisms.
  • the viscous initial product is, before being sent to an aerator for forming a foam which is then divided and dried for obtaining the powdery porous product, mechanically and/or thermically treated with a thermomechanical treatment machine, such as an extrusion machine or a heat exchanger with a scraped surface.
  • a thermomechanical treatment machine such as an extrusion machine or a heat exchanger with a scraped surface.
  • gas is mixed to the material produced by the thermomechanical treatment machine, this gas may be directly introduced into this machine and/or into the aerator.
  • WO-A-2008/046996 and WO-A-2013/185941 both teach that a mechanical and/or thermal treatment by an ad hoc thermomechanical treatment machine, notably an extrusion machine, is indispensable for “preparing” the viscous material at its admission into the aerator for forming foam, notably by lowering the viscosity of this material before its admission into the aerator.
  • an aerator is a mechanical mixer which is not designed for acting on too strongly viscous materials.
  • thermomechanical treatment machines notably extrusion machines
  • these thermomechanical treatment machines are mechanically complex pieces of equipment with systems of gears and reducers, sometimes provided with bearings and rotating joints, as well as with screws, scrapers with a rotating axis, these pieces of equipment being generally thermoregulated, at variable speed and sometimes equipped with vacuum application systems.
  • the aforementioned thermomechanical treatment machines are too bulky and require amounts of several kilograms, for example between 10 and 50 kg, for achieving the manufacturing of porous powder. More globally, it is understood that the application of methods using such thermomechanical treatment machines is costly in raw material and requires place on the ground, personnel for operation and a significant investment in sophisticated apparatuses.
  • WO-A-2013/185941 contemplates an alternative to the continuous production of powdery porous products, by resorting to a discontinuous method: for this, the viscous initial product is placed in a hermetic enclosure which is stirred, from the pressure inside the enclosure being generated by injection of a gas. Thus, the gas, which is discontinuously injected into the enclosure, pressurizes the latter and is partly dissolved in the viscous product. This enclosure is then mechanically stirred, either manually or by means of an ad hoc mechanical system. In practice, the efficiency of the mixing is not rarely controlled, the latter being subsequently taken out of the enclosure so as to be directly divided and dried. It is understood that this discontinuous alternative, proposed in WO-A-2013/185941 is suitable for producing very small amounts of powdery porous products, but it remains tedious to apply and may be controllable.
  • the object of the present invention is to improve the methods and installations for continuous production of powdery porous products, by simplifying them, notably in the case when the amount of raw material is small.
  • the object of the invention is a method for producing a powdery porous product, wherein:
  • thermomechanical treatment machine such as an extrusion machine
  • a thermomechanical treatment machine is not indispensable for making the viscous initial product capable of being admitted into an aerator.
  • the use of a conventional pump is possible for transferring as far as the aerator the viscous initial product as such, i.e. notably without any substantial heat treatment and without any significant mechanical treatment, i.e. without any heat treatment and without any mechanical treatment other than those exclusively resulting from the pumping with the pump, in other words from the suction, from the pressurization and from the discharge through this pump.
  • the embodiment of this pump is not limiting of the invention.
  • the viscous initial product pressurized by the pump, is admitted by the discharge of the pump while gas is injected: under the effect of the discharge pressure of the pump and of the injection pressure of the gas, the viscous initial product is, in spite of its strong viscosity, mixed with the gas by the aerator, so as to form a liquid foam.
  • the liquid foam is, under the effect of the pressure prevailing in the aerator, continuously pushed towards a continuous treatment device, placed downstream, which divides this liquid foam into particles and which dries these particles, this device for example being an atomization tower optionally followed by a fluidized bed.
  • the aforementioned pump has the exclusive function of transferring the viscous initial product towards the aerator, with pressurization compatible with this transfer and with the division followed by drying, at the outlet of the aerator, of the liquid foam formed by this aerator.
  • the pump efficiently replaces a more complex mechanical system and simplifies the production method, in this sense that a single gas injection is only used, i.e. that in the aerator, one operates with small amounts of raw material, for example between 1 and 20 kg/h, the initial investment is reduced, the operating and maintenance costs are reduced, and a more compact production installation is proposed than with an extrusion machine or another similar machine for thermomechanical treatment.
  • FIG. 1 is a schematic view of an installation according to the invention
  • FIG. 2 is a flow chart of a method according to the invention.
  • FIG. 3 is a flow chart of an alternative of the method, according to the invention.
  • FIG. 1 is illustrated an installation 1 for producing a powdery porous product P 3 .
  • the installation 1 is able to apply the production method illustrated in FIG. 2 .
  • the installation 1 comprises a preparation device 10 which, during a corresponding preparation step 110 , prepares a viscous initial product P 1 from a raw material M.
  • the raw material M is the viscous initial product, is obtained from a solution, suspension or emulsion in a solvent, notably an aqueous medium, containing:
  • the preparation device 10 is designed for, during the preparation step 110 , obtaining from the raw material M, the viscous initial product P 1 so that the latter has, at the outlet of the preparation device, a temperature comprised between 5° C. and 70° C., as well as a viscosity, at the temperature for making available the viscous initial product P 1 at the outlet of the preparation device 10 , greater than 100 mPa ⁇ s, or even 200 mPa ⁇ s, or even 500 mPa ⁇ s. It will be noted that usually “mPa” corresponds to “milli-Pascal”, i.e. 10 ⁇ 3 Pa. In other words, at the end of the preparation step 110 , the viscous initial product P 1 , prepared from the raw material M, is at its temperature of availability at the outlet of the preparation device 10 , highly viscous.
  • the preparation device 10 falls under a technology known per se, notably selected according to the raw material M.
  • the preparation device 10 which operates in free air or optionally in vacuo, comprises a system for metering a liquid and/or a solid, and/or a mixing system and/or a concentration system, notably by evaporation, and/or a separation system, notably by centrifugation or by a selective membrane, and/or a homogeneization system, and/or a colloidal milling system, and/or a heating/cooling system notably for maintaining temperature, for example by means of pieces of equipment with a jacket or thermoregulated pieces of equipment.
  • the ingredient(s) of the raw material M is(are) mixed and/or concentrated, notably by evaporation, and/or heated/cooled, notably maintained at a temperature.
  • the preparation device 10 advantageously gives the possibility of making available the viscous initial product P 1 in a continuous way, in order that this viscous initial product P 1 is treated by the remainder of the installation 1 with view to continuously producing the powdery porous product P 3 .
  • the installation 1 further comprises a pump 20 which, during a transfer step by pumping 120 , transfers the viscous initial product P 1 , leaving the preparation device 10 , as far as an aerator 30 , described in more detail subsequently.
  • the suction of the pump 20 is therefore connected to the outlet of the preparation device 10 , while the discharge of the pump 20 is connected to the inlet of the aerator 30 .
  • the pump 20 falls under a technology known per se, capable of transferring as such the viscous initial product P 1 from the outlet of the preparation device 10 to the inlet of the aerator 30 , in other words of transferring, from the preparation device 10 to the aerator 30 , the viscous initial product P 1 as available at the outlet of the preparation device 10 , without modifying its composition and its density, as well as without modifying substantially its viscosity and therefore the thermomechanical characteristics influencing this viscosity.
  • a marginal variation in the viscosity of the initial product P 1 may occur between the suction and the discharge of the pump 20 , because of the pressurization of the product P 1 and, optionally, because of a very slight heating of the product P 1 , but, overall, in tiny proportions, typically less than 2%.
  • the pump 20 is a single screw pump, a pump with gradual cavity, a lobe pump, a pump with two screws, etc.
  • the pump 20 has the exclusive function of transferring the viscous initial product P 1 from the preparation device 10 to the aerator 30 , by pressurizing the product P 1 .
  • the pump 20 thereby develops a discharge pressure comprised between 3 and 20 bars, preferably between 5 and 10 bars, at the relevant temperature and viscosity for the viscous initial product P 1 transferred, the latter being typically made available at the outlet of the device 10 substantially at atmospheric pressure.
  • the aerator 30 mixes the viscous initial product P 1 , discharged by the pump 20 , with a gas G, injected into the aerator 30 , in order to obtain a liquid foam P 2 .
  • the aerator 30 by itself falls under a technology known per se: this aerator 30 is a mechanical stirrer which stirs, intensely agitates the material which is admitted therein.
  • this aerator 30 is a mechanical stirrer which stirs, intensely agitates the material which is admitted therein.
  • the mechanical action of the aerator 30 is applied while the gas G is injected into the inside of the aerator in order to induce the porosification of the viscous initial product P 1 .
  • the aerator 30 is able to initiate and efficiently conduct the porosification of the viscous initial product P 1 , until the liquid foam P 2 is obtained. It is understood that, inside the aerator 30 , the porosification of the material is gradual from the inlet as far as the outlet of the aerator 30 , the liquid foam P 2 continuously leaving the aerator, under the effect of the pressure prevailing in this aerator.
  • the liquid foam P 2 being intended to be, at the outlet of the aerator 30 , divided into particles having a non-negligible liquid phase as explained subsequently, the variation of density between the viscous initial product P 1 and the liquid foam P 2 formed at the outlet of the aerator is advantageously under control.
  • the specific gravity of the liquid foam P 2 leaving the aerator 30 is thus comprised between 25 and 80% of the specific gravity of the viscous initial liquid P 1 .
  • the aerator 30 is a static or dynamic aeration apparatus.
  • the aerator 30 is for example a mixer with fixed helicoidal parts.
  • the aerator 30 for example consists of an apparatus provided with stirring blades or pins mounted on a rotating shaft in a stator, comprising an enclosure generally provided with parts attached on the internal wall of this enclosure and promoting the mixing.
  • the gas G injected into the aerator 30 , is preferably carbon dioxide. This being as non-limiting alternatives, the gas G may also be air, steam, nitrogen or one of its oxides.
  • the installation 1 also comprises a continuous treatment device 40 for liquid foam P 2 which, during corresponding division 141 and drying 142 steps, treats the foam P 2 so as to divide it and to dry it in order to obtain the powdery porous product P 3 having a dry material level greater than 90%.
  • the continuous treatment device 40 falls, as such, under a technology known per se.
  • this device includes, in series an atomization tower 41 with hot air, typically between 100 and 250° C., and a fluidized bed 42 : the liquid foam P 2 , admitted at the inlet of the atomization tower 41 is divided therein by spraying, the particles of the thereby divided foam being then dried in a hot air stream during their passing into a drying enclosure being part of the atomization tower. This drying is, if need be, completed in the fluidized bed 42 .
  • the fluidized bed 42 is absent, the division 141 and drying 142 steps then being exclusively ensured by the atomization tower 41 .
  • the atomization tower with hot air 41 may be replaced with a cold atomization system, including an enclosure, into which is pushed the liquid foam P 2 , receives a cold gas with controlled humidity, this cold gas may be cold air, typically between 10° C. and 60° C., or an expansed gas applying a negative temperature. Details and alternatives of the application of these division 141 and drying 142 steps are moreover provided in WO-A-2008/046996, as well as in WO-A-2013/185941, to which the reader may refer to if necessary.
  • the liquid foam P 2 is, at the outlet of the aerator 30 , continuously pushed into the inlet of the continuous treatment device 40 , and then, at the device 40 , is partly or even totally divided into particles, typically by spraying at the inlet of this device 40 .
  • the remainder of the gas G, which has dissolved into the liquid phase of particles of liquid foam, tends to evaporate during the drying, by generating pores in the constitutive material of the grains of the final product P 3 .
  • the method of FIG. 3 gives the possibility of operating partly in a discontinuous way.
  • the viscous initial product P 1 is made available as a storage S, for which the contents are resumed, discontinuously, by the pump 20 , the corresponding step for transfer by pumping 120 and the subsequent steps 130 , 141 and 142 with view to continuously producing the powdery porous product P 3 being identical with those described facing FIG. 2 and therefore bearing the same numerical references in FIG. 3 .
  • the storage S is, prior to the application of this alternative of the production method, supplied with the viscous initial product P 1 , the latter being for example prepared by the preparation device 10 or a similar device, if necessary offset relatively to the pump 20 , to the aerator 30 and to the treatment device 40 .
  • the storage S is applied by means for example of a storage pan of the viscous initial product P 1 , so as to maintain the latter under satisfactory conditions, notably temperature conditions, for making available the viscous initial product P 1 for the purposes of production of the powdery porous product P 3 .
  • the suction of the pump 20 is supplied by the storage S, the continuation of the method being identical with the one described earlier in connection with FIG. 2 .
